Well, if it sounds like "popping", it sounds as if you have a a problem. :)
I'm not sure what a "clamshell" is, here.
This transformer has metal
(presumably steel) sheet laminate for the core, metal sides enclosing
the windings, and bolts through the sides and the lamination layers to
hold it all together. It's a common design for vacuum-tube-era power
transformers, in my (admittedly limited) experience.
I'm referring to the metal sides, held in place with through-bolts as being
the "clamshell". Sorry that I can't think of a more descriptive term. If
you thought your transformer was big, you should see some of the units used
in the early color TVs.
I'd still recommend that you tag the "stubs" in the scope after you remove
the transformer. It's not a given that any replacement unit will employ
the same color coding, although there was a convention of sorts
(Black=primary, Green=6.3v filament with Green/striped as CT; Yellow=5V
rectifier, Red=High voltage), but you couldn't depend on it with absolute
certainty.
Cheers,
